PURPOSE:To improve service life characteristic by controlling electrode potential (electromotive force) of fuel battery body through the supply system of fuel gas and oxidation agent gas and a load apparatus. CONSTITUTION:During the start of fuel battery body 1, a controller 13a having received measured value signals from an internal pressure measuring apparatus 9, internal temperature measuring apparatus 10 and supply flow rate measuring apparatuses 2, 3 controlls the fuel gas and oxidizing agent gas supply regulator valves 4, 5 and regulates the flow of supply. A controller 13b having received measured value signals from pressure/temperature measuring apparatuses 9, 10 and electromotive force measuring apparatus 11 sequentially changes the load of preliminary loading apparatus 12c and controls it so that the specified target voltage value can be obtained. As the preliminary loading apparatus 12c, a multi-stage fixed resistor is used and the specified target voltage value is selected to a value corresponding to the condition of minimum partial loading operation of real loading operation. When the specified target voltage value is obtained, the operation is continued after the loading condition is switched to the real load 12b so as to control the starting power within the specified range.
